Introduction:

Quality of life, as a multidimensional construct, comprises physical, social and cultural aspects of people with intellectual disabilities; therefore, it is necessary to have adapted and validated instruments to recognize the specific needs of this population.

Objective:

To make a cross-cultural adaptation for Colombia of the KidsLife Scale for people with intellectual disabilities.

Materials and methods:

Instrumental study done in phases. First, a preliminary review of the scale was made by the researchers; then, the validity of the content was verified by seven experts who assessed relevance, impact, compliance and grammatical adequacy; finally, a pilot study was carried out with 30 people to determine reliability and discriminative power.

Results:

In terms of content validity, the weighted concordance coefficients for agreement among judges and dimensional concordance were good. Regarding reliability and discriminative power, very good internal consistency was found for the whole scale (Cronbach's alpha of 0.95) and 52 items under discriminative power (p>0.1).

Conclusions:

The adapted and validated KidsLife Scale for Colombia will strengthen the care processes from different dimensions of quality of life, focused on the needs of the person with intellectual and multiple disabilities, families and support professionals.
